within 4 feet of the modem that is the source of the Wi-fi. I don't think I experimented with Wi-fi off (and Mobile Data on), if I did, the phone behaved the same way.
Right now, with the old SIM card in the phone (as it's been since October after re-replacing the new with the old card) I have 2 bars (out of 5), but I'm also connected to Wifi (I don't think the bars are significant if I'm connected to Wi-fi). If I turn Wifi off on my phone and turn on Mobile Data, the Wifi symbol on my phone goes away, and a "LTE" shows up. I still have 2 bars.
I have been away from home lately many times and walking several miles operating on Mobile Data on and Wi-fi off (again with the old SIM card, and including recently) and everything is fine.
I have no experience with the NEW card away from Wi-fi, I don't think. I can't tell you how many bars it had with the new SIM card, I'm sure I looked at it, but I can't guarantee that I did. But as I said with previous replies, Internet browsing went just fine with the new card, whereas trying to text message or use my phone app gave me some error message about the network, and it wasn't a message about signal strength. i just can't find my notes from last October where I wrote down the error messages.
As for CC switching the network, I don't think so, not yet. My phone works just the same way as it did years ago, last year before the period where I had the new SIM card in briefly (a few weeks), and since October when I had the old card back in. In all these old SIM card periods, I never had problems with any aspect of my phone due to low signal strength or incompatible network or any of that.
But for sure CC wants me and other obstinant troglodytes to switch to their new network. With the new SIM card, and it being properly activated, that's what will happen as I understand things.
Thanks much for reading all this and for replying above.
